I have to say that after it was all said and done, I’m keeping 3.5.9. It works and it works like I want it to. I got 4.0.1 working, but I couldn’t figure out what I needed to do to get it working and looking like I wanted it to work and look(mainly, exactly like 3.5.9). I just wish I could turn off the upgrade notice for this plug-in as I don’t plan on changing off of 3.5.9 until I’ve heard that the new versions are similar to this one.
You can search for Username in the plugin editor and the form size is right below it at 20 characters. I changed it to 15 for my blog. Right below that will be the Password section where you can change that form size as well.
It’s the size=”XX” lines right after the find the key spots.
Crashed my entire site, same exact error as the above poster. Had to move it out of the plugins directory to get my site back up.
